My first project done completely in TDD was an open source one in 2002.
You can still find it here:
Now at work I'm working mostly in TDD but not everybody in our team does, that's fine provided the wrote the tests at the end of the day.
We also wrote a complete gwt-gae application using TDD for the core part.
I cannot release that code but I'm working on a complete example project done in TDD for GWT, that is using TDD also in the UI.
As soon as I'll finish (Christmas holidays) I'll post it here
